United States President Donald Trump on Sunday warned Iran of bombings if Tehran did not reach an agreement with the US over its nuclear program.
Trump also said that secondary tariffs would be imposed on Iran if a deal is not made.
"If they don't make a deal, there will be bombing...But there's a chance that if they don't make a deal, I will do secondary tariffs on them like I did four years ago," Trump told NBC News.
After assuming the president's office in 2018, Trump withdrew the US from the nuclear deal with Iran. Trump has insisted that Iran must not develop nuclear weapons.
A report in February by the UN's nuclear watchdog said Iran has accelerated its production of near weapon-grade uranium.
Trump's remark came after Iranian President Masoud Pezeshkian rejected direct negotiations with the US over its nuclear program.
"We don’t avoid talks; it’s the breach of promises that has caused issues for us so far,” Pezeshkian said in televised remarks during a Cabinet meeting. “They must prove that they can build trust.”
It is not clear whether Trump would accept any indirect negotiations.
Meanwhile, Iranian parliament speaker Mohammad Bagher Qalibaf on Friday said that American bases in the Middle East are vulnerable to Iran's attacks.
"The Americans themselves know how vulnerable they are. If they violate Iran’s sovereignty, it will be like a spark in a gunpowder depot, setting the entire region ablaze. In such a scenario, their bases and their allies will not be safe," he said.
Iran's Supreme Leader Ayatollah Ali Khamenei in his response in February warned that talks with the US "are not intelligent, wise or honorable".
Trump had sent a letter to Iran's leadership seeking negotiations on the nuclear deal in March. He had then warned that if Iran does not negotiate, "it will be ugly for them".
